The directive mandates changes to the Aircraft Flight Manual and updates to navigation software to mitigate erroneous guidance issues in certain flight management system procedures.
What changed
This directive introduces operational limitations for affected airborne navigation procedures within the Flight Management System and requires amendments to the Aircraft Flight Manual referencing the updated Thales FMS User Manual. Additionally, it mandates updating the navigation database to remove problematic procedures as defined in the Thales Service Information Letter. These changes aim to prevent erroneous guidance caused by software issues in the FMC2 NAVM.
Why it matters
The directive is critical for aviation professionals because the software issues in the FMC2 NAVM can compromise aircraft safety margins during navigation procedures. Operators and maintenance teams must ensure compliance to avoid potential flight safety risks. The amendment affects flight crew operations and requires specific training to handle the limitations and recovery procedures effectively.
